THE SMART PIPE THAT COMMUNICATES ITS LOCATION
Every year in France thousands of underground assets—like water and gas lines—
are damaged during digging work, simply because their exact location cannot be
determined accurately. Today there is a solution. Ryb has developed Eliot, a smart
piping system equipped with RFID chips capable of sending accurate location
information down to the centimeter at depths of up to 1.5 meters. The chips also
store information like the type of piping (water or gas), manufacturing date, serial
number, and diameter.
Eliot, which was developed in conjunction
with Leti, features RFID tags embedded
in the piping material at regular intervals
and a reading and detection device used
RFID technology was originally
developed for traceability applications.
The technology had to be modified to
detect and locate chips underground in
a variety of conditions.
Thanks to a patented antenna design,
transmission (at 13.56 MHz) remains
robust despite use in a wide range
of conditions. The antenna design is
patented. The RFID tags are also robust,
and can withstand the high temperatures
of the extrusion process.
Eliot is the world’s first communicating
